> pubsub is a great way to broadcast messages to gadgets, but the current
> implementation only allows gadgets to publish messages. The provided patch
> allows the container to publish messages too (using the same publish
> signature the gadgets use). The ability to subscribe and unsubsribe isn't
> needed because the container can already pass in a callback that is called
> whenever a message is received, which allows it to listen in on all channels.
> This improvement is useful because it allows a container to have global
> state, and communicate that global state to any interested gadgets. The best
> example is a common date control (in the container), and all gadgets can
> listen for date changes (through a channel that the container publishes
> changes to).
> There are two patches. The first implements the change and is minimal. The
> second changes the sample container example to show the change in action.
> The sample container is modified to add a button that does a container
> publish, and a new minimal gadget is introduced that responds to the publish.
> This second patch isn't intended to be applied to shindig, it''s just meant
> to provide an example of this improvement to whoever picks up this issue.
